In the middle of June this year  I booked a Princess Plus fare for a Hawaii Cruise early next year. The booking confirmation confirms the items included in the Plus package (drinks, fitness classes, premium desserts etc). It does not show the recently introduced Plus features (2x Casual Dining, Room Service etc) . Does anyone now whether these 'old' Plus fares will include the new features or will they remain as they were at the time of booking.   Thanks for any information you ca
